Breaking out of a foreach loop

When using a Cartesian or multigrid, the break statement does not directly exit the foreach loop. But is does on a tree-grid, making the behaviour grid dependent.

#include "grid/multigrid.h"

int main() {
  init_grid (4); // a 4 x 4 grid;
  int j = 0;
  foreach() {
    printf ("This is printed %d time(s)\n", ++j);

break statement not within loop or switch

    break;
  }
}

output

The line is printed N times as it breaks only the row iterator loop. See here.
